Bright days ahead for the Amiga world. AROS is doing well, AmigaOS4 is getting one heck of a machine in the AmigaOne X1000, and MorphOS continues its development at a brisk pace. Version 2.6 of MorphOS, currently in development, will add support for (G4, I'm assuming) PowerMacs, which, alongside support for the Mac Mini and eMac, gives MorphOS a solid base of used hardware to run on.

This issue is voided by hibernation, though, but then boot times become important again.

With hibernation, boot times is scarcely more than loading a ram image off the hard disk. That's fine for 2GB of ram. I wonder how practical it is for 16GB?

oftware performance degrades with uptime. There's always a memory leak somewhere, some applications leave processes in the background wasting CPU time for unknown purposes even after they're closed, some crashes have long-term consequences... Fetching a fresh OS image from the disk allows one to go back in a clean state where software runs at full speed and maximum reliability.

I have to disagree with this statment. This isn't the days of Windows 98. My system doesn't degrade as uptime increases, and Windows does a fine damn job of shutting down processes. Also, the software I use is well written, and doesn't normally doesn't leak memory. If it does, I restart only the app in question, and sanity is returned.
